It does do screen shots by holding two fingers for one second on the side touch panel. I don't know about video. Also you can't use larger than a 32 gb card in the goggles.My understanding is that the SD slot on the DJI Goggles is only for playback/viewing. In other words, you would take the card out of the Mavic and place it in the goggles. Yes that sounds stupid
It does put the two finger snapshots on the card though.. i tested this last nite.
oops.. i hadnt got that far on the hdmi to realize its input only.Would be nice indeed, especially since the livestream as shown on the goggles is perfectly smooth while for some reason the video cache stored on the mobile device is stuttery.
No chance on HDMI, it's input only (unfortunate for so many reasons).
